I have a 4 month old americauna who has been having eye problems for about a week. Her symptoms are swollen, itchy eyes. I seperated her from the rest of the flock and nobody else has these exact symptoms. Could these be allergies or a virus or something? I started her and everybody else on duramycin 10 a few days ago. Should I keep with this and what could her ailment be? When I let her out into the yard, she tries to open her eyes and scratch around for food. I'm afraid she hasn't been eating so I've been trying to force feed her but she doesn't want anything to do with that. I do get her to drink her treated water with a syringe. I just have no idea what it could be.
